What's actually doing the work

SPF / Sunscreen
Zinc Oxide / Titanium Dioxide / Broad-Spectrum UV Filter
Mineral
The single most evidence-backed anti-aging intervention. UV drives 80–90% of visible skin aging, hyperpigmentation and skin cancer risk. SPF 30 blocks ~97% UVB; SPF 50 blocks ~98%. Mineral filters (zinc oxide, titanium dioxide) physically deflect UV; chemical filters absorb and convert UV to heat.
